Kendigs DID issue cataloged cards in the ACC under E236 for the flags.....a (24) card set that aren't particularly tough to get. The text on the back of these cards matches the text on the back of the BB cards minus some of the bottom as the Flag cards are taller than the BB cards would have been. I'd assume the E236 cards to be from the same timeframe as the BB cards.
